Abstract
An air blower includes a base having a raised column, an arcuate recess between an inner face of the base and an outer periphery of the column and a bottom nozzle, a fan assembly mounted on top of the raised column to generate air flow and having a conical top face, and a cap securely combined with the base and having a top nozzle combined with the bottom nozzle to form an outlet so that the air flow generated by the fan assembly is first directed to the inner face of the cap and then spiraled downward along the raised column to escape the outlet via the arcuate recess.
